CENTRAL PROCESSOR UNIT (CPU) CARD
The central processor unit (CPU) card holds the circuitry that allows
the system to connect to, and communicate with, the following
interfaces:
• An external personal computer
• Externally connected alarms
• Eight general-purpose inputs (GPIs)
• Eight general-purpose outputs (GPOs)
• Two separate local area network (LAN) connections for
Ethernet-based communication with a network
• An external interface that provides additional GPIs and GPOs
In addition, the card’s operational memory holds up to four complete
preassigned system configurations to access and activate either
directly from the CPU card or from the ECS application.
CREATING AND STORING SYSTEM CONFIGURA-
TIONS
A “configuration” is a complete set of operating parameters for the
system which includes talk and listen paths for each connected
intercom panel. Depending on the interfaces installed, the
configuration can also include more sophisticated features such as
paging, call signaling, interrupt foldback (IFB), ISO, groups, automatic
DTMF dialing, routing, and many other features.
When an external computer is connected to the matrix the system
administrator can retrieve the current configuration information stored
in the CPU microprocessor’s memory (using the Eclipse Configuration
Software) and display the configuration on the computer’s screen.
The system administrator can then apply the current configuration,
modify it, or create a new configuration with the Eclipse Configuration
Software. If the system administrator creates more than one
configuration the unused configurations can be stored on the
computer’s hard disk or on CD-ROM to use later, allowing the system
to be reconfigured as required.
The CPU card itself will store up to four complete configurations in its
operational memory that can be applied either directly from the CPU
card or from the connected computer.
SETTING THE DEFAULT IP ADDRESS
The CPU card LAN ports can be reset to their default IP addresses by
pressing and holding the ‘ENG’ and ‘FULL RESET’ buttons on the
CPU front card and then pressing the ‘RESET’ button at the top and
then holding the ‘ENG’ and ‘FULL RESET’ buttons until the card
Note: General Purpose
Outputs are also referred to
as “relays.”
Note: If the configuration
does not remain in memory
after you power off, please
see the first section in
Chapter 3, “Reconnecting the
CPU Card’s Backup Battery.”
